Learning how to relax during pregnancy is important.​A 30- to 60-minute nap during the day makes you more alert, sharpens memory, and generally reduces feelings of fatigue. A study by the National Sleep Foundation found that more than half of pregnant women take at least one nap during the workweek, and 60 percent take at least one weekend nap

Time your naps carefully, though. Napping too late in the day (or for too long) can interfere with your sleep at night.Don't work out late in the dayGet your exercise early enough in the day to give your body time to wind down after a workout.Working out too close to bedtime can rev you up and even rob you of deep sleep by interfering with your natural sleep cycle. Try to finish exercising at least three to four hours before you turn in for the night.Practice relaxation techniquesLearn about sleep-inducing techniques such as guided imagery, deep breathing, or progressive muscle relaxation.Don't let your "worry list" worry youKeeping paper and pen next to your bed may help relieve middle-of-the-night anxieties. When you wake up thinking about all the things you need to do the next day, write them down.If writing down your thoughts makes you worry even more, finish making your list of questions, concerns, and things to do at least an hour before bedtime. Then try to put it out of your mind until morning.Enroll in a classIf you're anxious about labor and delivery, baby care, or breastfeeding, sign up for a class. Knowing what to expect can help put you at ease. You might also benefit from the camaraderie of other pregnant women.Courtesy: www.babycenter.com
